App crashes on first launch ios 9.2

[SreeharshaJois]

Precondition: Make sure that app is not installed on the device.

Test environment details: cordova-ios-4.0.1 cordova:6.1.1 appsflyer plugin version:4.0.1

Steps to reproduce: 1.Install app from itunes/xcode 2.Open the app

Issue seen: App is crashing only on first time launch in iOS 9.2. Subsequent launch crash is not seen. This issue can be found in the forked plugin https://github.com/AppsFlyerSDK/PhoneGap as well.

Initial Analysis from log: stringByEvaluatingJavaScriptFromString method call needs to be done from main thread which is not happening on first launch

-(void)onConversionDataReceived:(NSDictionary) installData { NSError error; NSData jsonData = [NSJSONSerialization dataWithJSONObject:installData options:0 error:&error]; if (jsonData) { NSString JSONString = [[NSString alloc] initWithBytes:[jsonData bytes] length:[jsonData length] encoding:NSUTF8StringEncoding]; [[super webView] stringByEvaluatingJavaScriptFromString: [NSString stringWithFormat:@"javascript:window.plugins.appsFlyer.onInstallConversionDataLoaded(%@)", JSONString]]; } else { NSLog(@"%@",error); } }

Below is the crash log: _WebTryThreadLock(bool), 0x7fc24c204210: Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread.
