    Quick Start

    ///  Obj-C Example
    @interface TestViewController : UIViewController <ProximiioDelegate>
    - (void)proximiioPositionUpdated:(CLLocation*)location {
        NSLog(@"User position updated to: %@", location);
    //Set the delegate and authorize
    - (void)viewDidLoad
        [super viewDidLoad];
        /// force request permission with background, use NO if you don't need background
        [[Proximiio sharedInstance] requestPermissions: YES];
        /// start auth
        [[Proximiio sharedInstance] authWithToken:token callback:^(ProximiioState result) {
            /// if auth succeed
            if (result == kProximiioReady) {
                [[Proximiio sharedInstance] enable];
                [[Proximiio sharedInstance] startUpdating];
                [[Proximiio sharedInstance] setDelegate: self];
                [[Proximiio sharedInstance] setBufferSize:kProximiioBufferMini];
                [Proximiio sharedInstance].desiredAccuracy = kCLLocationAccuracyBestForNavigation;
    //  Swift Example
    import Proximiio
    class MainViewController: UIViewController {
        override func viewDidLoad() {
            let token = "APPLICATION_AUTH_TOKEN"
            /// force request permission with background, use false if you don't need background
            /// show the main application
            Proximiio.sharedInstance()?.auth(withToken: appToken, callback: { state in
                /// if boot up of proximiio went fine
                if state == kProximiioReady {
                    /// startup
                    /// set delegate
                    Proximiio.sharedInstance()?.delegate = self
    // MARK: - Proximiio Delegate
    extension MainViewController: ProximiioDelegate {
        func onProximiioReady() {
        func proximiioFloorChanged(_ floor: ProximiioFloor!) {}
        func proximiioPositionUpdated(_ location: ProximiioLocation!) {

    You can get started with iOS SDK in less than 5 minutes! All you need is a account and obviously the SDK itself.

        <string>Beacon to increase location position </string>
        <string>Allow bluetooth for improved beacon operation</string>
        <string>Allow Background Location updates for Event triggering while the App is in background</string>
        <string>Allow always usage for permanent positioning support</string>
        <string>Allow location updates for basic SDK operation</string>
        <string>Allow motion detection for improved positioning</string>
    * If you are planning to use the SDK in background too please add this to <code>Info.plist</code>

    Access utilizes a singleton pattern to coordinate all functions and events. It simplifies access from anywhere in your code to the functions.

    To get a pointer to the singleton, simply call:

    ///  Obj-C Example
    #import <Proximiio/Proximiio.h>
    ProximiioManager *proximiio = (ProximiioManager *)[Proximiio sharedInstance];
    //  Swift Example
    let proximiio = Proximiio.sharedInstance()

    Authentication allows you to authenticate in two ways - via an auth token and an application name or by using your email and password. Both methods allow you to later change the application freely.

    Authentitication only needs to be done once before using the API.

    To authorize with your authentication token:

    ///  Obj-C Example
    [[Proximiio sharedInstance] authWithToken:YOUR_AUTH_TOKEN];
    //  Swift Example
    Proximiio.sharedInstance()?.auth(withToken: appToken, callback: { state in }

    Positioning Engine Control

    You can manually trigger sdk positionining engine by calling

    ///  Obj-C Example
    [[Proximiio sharedInstance] enable]


    ///  Obj-C Example
    [[Proximiio sharedInstance] disable]

    This will keep instance in background and authorized, but it will not perform any location source updates, therefor is usefull in situation when constant position updates are not necessary and leads to more optimal battery usage.

    Resetting the API (GDPR Compliance)

    In order to meet GDPR compliance, you can reset the API and generate a new user (visitor) by calling the following function. It will reset all buffered positions and floor changes, so all events will be triggered again as the device is treated like new.

    ///  Obj-C Example
    [[Proximiio sharedInstance] resetAndRefresh];

    Background mode

    SDK support background mode positioning too, in order to use this, please proceed updating your Info.plist file adding this key/value:


    And then initialize the code using:

        ///  Obj-C Example
        [[Proximiio sharedInstance] requestPermissions: YES];
        /// using NO it will allow you to get position only on app in foreground
        /// Swift Example


    The new SDK allows you to apply post processing operation in a queue mode over the position calculated by the hardware interfaces (e.g. gps, beacon).

    In this way the value can be tweaked or improved to provide a better or more complete experience to the user.

    We provide some ready built processors:

    For further details please refer to Github repository.

    In order to use these you have just to add an extra pod to your Podfile:

    pod "ProximiioProcessor"

    Then in order to use those is just enough enque the processor before the SDK enable.

    ///  Obj-C Example
    #import <Proximiio/ProximiioProcessor.h>
    /// add just after
    [[Proximiio sharedInstance] enable];
    /// add snap pre-processor
    ProximiioSnapProcessor *snap = [ProximiioSnapProcessor new];
    snap.threshold = 5.0;
    [[[Proximiio sharedInstance] locationManager] addProcessor: snap];
    //  Swift Example
    import ProximiioProcessor
    /// add just after
    /// add snap pre-processor
    let snap = ProximiioSnapProcessor()
    snap.threshold = 5.0
    Proximiio.sharedInstance()?.locationManager.addProcessor(snap, avoidDuplicates: true)

    Synchronization and caching

    The new SDK introduce data syncronization and caching.

    It works with incremental delta and supports amenities, features and all the data used by SDK.

    In order to preload them you can add those few lines of code after the auth is successfull (swift) or onProximiioReady delegate is invoked.

    ///  Obj-C Example
    [[Proximiio sharedInstance] sync:^(BOOL completed) {
    //  Swift Example
    /// force sync all data
    Proximiio.sharedInstance()?.sync({ _ in

    Object Management SDK provide you access to the objects connected to the appToken provided in the auth function.

    You can access objects in this way:

    ///  Obj-C Example
    /// places
    NSArray *places = [[Proximiio sharedInstance] places];
    /// floors
    NSArray *floors = [[Proximiio sharedInstance] floors];
    /// departments
    NSArray *departments = [[Proximiio sharedInstance] departments];
    /// geofences
    NSArray *places = [[Proximiio sharedInstance] geofences];
    /// inputs
    NSArray *inputs = [[Proximiio sharedInstance] inputs];
    /// privacy zones
    NSArray *privacy = [[Proximiio sharedInstance] privacyZones];
    //  Swift Example
    /// places
    let places = Proximiio.sharedInstance()?.places
    /// floors
    let floors = Proximiio.sharedInstance()?.floors
    /// departments
    let departments = Proximiio.sharedInstance()?.departments
    /// geofences
    let geofences = Proximiio.sharedInstance()?.geofences
    /// inputs
    let inputs = Proximiio.sharedInstance()?.inputs
    /// privacy zones
    let privacy = Proximiio.sharedInstance()?.privacyZones

    If you are know the uuid of a single object you can use a dedicated helper to get it:

    ///  Obj-C Example
    ProximiioPlace *place = [[Proximiio sharedInstance] getPlace: "XXXXXXXXXXX"];
    /// swift
    let place = Proximiio.sharedInstance()?.getPlace(uuid: "XXXXXXXXXXXX")

    Inputs (General)


    While all inputs are saved within the same class ProximiioInput, the managing system to add and update them differentiate between their types (iBeacon, Eddystone, Custom).

    You can cast the object to obtain all the information using this classes: ProximiioIBeacon, ProximiioEddystone.

    Object relations

    Example of relations.

    ///  Obj-C Example
    //To get the parent of a floor (a place) you can either call
    ProximiioPlace *placeParent = (ProximiioPlace*)[floor parent];
    //or use the convenient function
    ProximiioPlace *placeConvenient = [floor place];
    //Both will return the same!

    The ProximiioResource is the base class for the other objects like ProximiioPlace, ProximiioFloor, ProximiioDepartment, ProximiioInput and ProximiioGeofence.

    These objects are in a hierarchical relation to each other.

    You can either use the parent function of the ProximiioResource class, or use the convenience functions of each subclass to get the upper levels. See the example on the side. Some objects are orphans, so you should always check for nil values!


    SDK exposes several data structure that can be used interact with user.

    One note, we you have to interact with dictionaries (e.g. metadata), you can access the metadata value for a specific key (e.g. keyOne) in this way:

    let value = place.metadata["keyOne"] as? String

    In order to access the value you have always to cast to the proper format you are expecting.

    Here the model structure you can access to:


    It's the model that holds information about a department, the basic structure provides:


    It's the model that holds information about a floor, the basic structure provides:

    ProximiioGeofence / ProximiioPrivacyZone

    It's the model that holds information about a geofence (or a privacy zone), the basic structure provides:


    It's the model that holds information about an input, the basic structure provides:


    It's the model that holds information about a place, the basic structure provides:


    The delegate ProximiioDelegate of the base class plays a huge role in the use of the SDK.


    An event will be send when the user entered or exited a defined ProximiioGeofence.

    /// Objective-C
    - (void)proximiioEnteredGeofence:(ProximiioGeofence*)geofence;
    - (void)proximiioExitedGeofence:(ProximiioGeofence*)geofence;
    /// Swift
    func proximiioEnteredGeofence(_ geofence: ProximiioGeofence!) {
        // notification on entering a geofence
    func proximiioExitedGeofence(_ geofence: ProximiioGeofence!) {
        // notificaion on exit a geofence


    An event will be send whenever the user position is updated through an input.

    /// Objective-C
    - (void)proximiioPositionUpdated:(CLLocation*)location;
    /// Swift
    func proximiioPositionUpdated(_ location: ProximiioLocation!) {}


    An event will be send when an iBeacon is found, updated or lost.

    /// Objective-C
    - (void)proximiioFoundiBeacon:(ProximiioBeacon*)beacon isRegistered:(BOOL)registered;
    - (void)proximiioUpdatediBeacon:(ProximiioBeacon*)beacon isRegistered:(BOOL)registered;
    - (void)proximiioLostiBeacon:(ProximiioBeacon*)beacon isRegistered:(BOOL)registered;
    /// Swift
    func proximiioFoundiBeacon(_ beacon: ProximiioIBeacon!) {}
    func proximiioUpdatediBeacon(_ beacon: ProximiioIBeacon!) {}
    func proximiioLostiBeacon(_ beacon: ProximiioIBeacon!) {}


    An event will be send when an Eddystone Beacon is found, updated or lost.

    /// Objective-C
    - (void)proximiioFoundEddystoneBeacon:(ProximiioEddystoneBeacon*)beacon isRegistered:(BOOL)registered;
    - (void)proximiioUpdatedEddystoneBeacon:(ProximiioEddystoneBeacon*)beacon isRegistered:(BOOL)registered;
    - (void)proximiioLostEddystoneBeacon:(ProximiioEddystoneBeacon*)beacon isRegistered:(BOOL)registered;
    /// Swift
    func proximiioFound(_ beacon: ProximiioEddystoneBeacon!) {}
    func proximiioUpdatedEddystoneBeacon(_ beacon: ProximiioEddystoneBeacon!) {}
    func proximiioLostEddystoneBeacon(_ beacon: ProximiioEddystoneBeacon!) {}


    An event will be send when a network object is created, updated or deleted.

    /// Objective-C
    - (void)proximiioUpdatedApplications;
    - (void)proximiioUpdatedPlaces;
    - (void)proximiioUpdatedFloors;
    - (void)proximiioUpdatedDepartments;
    - (void)proximiioUpdatedInputs;
    - (void)proximiioUpdatedGeofences;
    /// Swift
    func proximiioUpdatedApplications() {}
    func proximiioUpdatedPlaces() {}
    func proximiioUpdatedFloors() {}
    func proximiioUpdatedDepartments() {}
    func proximiioUpdatedInputs() {}
    func proximiioUpdatedGeofences() {}

    AppStore Submission

    The SDK architectures for Simulator need to be removed before submitting your app. Go to your Project Settings => Build Phases and click the + located on top left part of the window to Add Run Script Phase.

    paste following code into script body of the created Run Script Phase

    # This script loops through the frameworks embedded in the application and
    # removes unused architectures.
    find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK
    FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)
    echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"
    for ARCH in $ARCHS
    echo "Extracting $ARCH from $FRAMEWORK_EXECUTABLE_NAME"
    echo "Merging extracted architectures: ${ARCHS}"
    lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"
    rm "${EXTRACTED_ARCHS[@]}"
    echo "Replacing original executable with thinned version"

    Make sure the created Run Script Phase is located below "Embed Frameworks" Phase.


    If the library produce error on build, try add these few lines at the bottom of your Podfile.

    post_install do |installer|
        installer.pods_project.targets.each do |target|
            target.build_configurations.each do |config|
                config.build_settings['SWIFT_VERSION'] = '5.2'
                config.build_settings['ENABLE_BITCODE'] = 'NO'


    Scan Triggering

    ///  Obj-C Example
    [[Proximiio sharedInstance] startUpdating];
    [[Proximiio sharedInstance] stopUpdating];
    //  Swift Example

    You can turn locationing on/off by using these methods.


    ///  Obj-C Example
    [[Proximiio sharedInstance] addCustomiBeaconUUID:@"F7826DA6-4FA2-4E98-8024-BC5B71E0893E"];

    You can add custom UUIDs that will be scanned for to the internal beacon scanner. This way the standard beacon delegate can be utilized further.

    - (void) addCustomiBeaconUUID:(NSString*)uuid;
