+# Papcorns Analytics iOS SDK -> Swift 5
+
+Add the following line to your Podfile
+
+```
+pod 'PapcornsAnalytics'
+```
+
+# Integrate the SDK into your app
+
+
+```
+import PapcornsAnalytics
+```
+
+Initialize PapcornsAnalytics in the `didFinishLaunching` or `didFinishLaunchingWithOptions` method of your AppDelegate file
+
+```
+ var appVersion = ""
+ if let versionString = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String {
+     appVersion = versionString
+ }
+ PapcornsAnalytics.configure(appId: "INSERT YOUR APP ID HERE", appVersion: appVersion)
+```
+
+Replace "INSERT YOUR APP ID HERE" string with id given to you
+
+# Setting User Id
+
+Before calling logEvent or logScreen you need to set  `PapcornsAnalytics.logEvent` with parameters [String:Any] whenever you need to trigger an event like in app purchases or signups etc.. , if there is no parameter then leave it with blank dictionary which is [:] .In event naming convension start with lowercased letter
+
+```
+PapcornsAnalytics.setUserId(userId : "")
+```
+
+## IMPORTANT !!!!!
+
+If you are using Revenuecat and Firebase as a receipt validation then you need also set Revenuecat userId because we are also getting logs from Revenuecat webhook . 
+
+So checking authentication everytime user goes into app might be a good idea with this function
+
+```
+func checkAuth(){
+    let cUser = Auth.auth().currentUser
+    if(cUser != nil){
+        PapcornsAnalytics.setUserId(userId: cUser!.uid)
+        Purchases.shared.identify(cUser!.uid, { (info, error) in
+            if let e = error {
+                print("Sign in error: \(e.localizedDescription)")
+            }
+        })
+        self.continueToSomething()
+    }else{
+        Auth.auth().signInAnonymously { (result, err) in
+            PapcornsAnalytics.setUserId(userId: (result?.user.uid)!)
+            Purchases.shared.identify((result?.user.uid)!, { (info, error) in
+                if let e = error {
+                    print("Sign in error: \(e.localizedDescription)")
+                }
+            })
+            self.continueToSomething()
+        }
+    }
+}
+```
+
+# Tracking Screens
+
+In  `viewDidAppear` function of your viewcontroller call  `PapcornsAnalytics.logScreen` with parameters [String:Any] ,  if there is no parameter then leave it with blank dictionary which is [:] 
+
+Setting a screenName parameter has a naming convention which is to put you context name first and then put "Screen" on top of it . For example if i am in HomeViewController log screen with name "HomeScreen". In log screen event naming start with uppercase letter
+
+```
+  override func viewDidAppear(_ animated: Bool) {
+      super.viewDidAppear(animated)
+      PapcornsAnalytics.logScreen(screenName: "XScreen", screenParameters: [:])
+  }
+```
+
+# Tracking Events
+
+Call  `PapcornsAnalytics.logEvent` with parameters [String:Any] whenever you need to trigger an event like in app purchases or signups etc.. , if there is no parameter then leave it with blank dictionary which is [:] .In event naming convension start with lowercased letter
+
+```
+PapcornsAnalytics.logEvent(eventName: "effectTapped", eventParameters: 
+    [ 
+        "effectName" : "Harry Potter",
+        "effectId" : "1sae1123asgasr"
+    ]
+)
+
+OR
+
+PapcornsAnalytics.logEvent(eventName: "weekly_trial_bought", eventParameters: [:])
+```
+
