Crash on Iphone simulators

[bananalopa]

Hi, could you help me?

Looks like plugin crashes the app when I am trying to use it with any iphone simulator in xcode.

Code in unity which causes this error is calling: PreciseLocale.GetLanguageID()

Output:
dyld: Symbol not found: __getLanguageID
Referenced from: /Users/admin/Library/Developer/CoreSimulator/Devices/EA30ED97-A267-4690-91C1-3D2642B825C5/data/Containers/Bundle/Application/A8F3B4C9-70DF-4E4C-B3AF-C5C8A4E1E8D6/mandala.app/mandala

Could you fix it or at least add handler that prevents the crash?

I ran into this too, and it’s unfortunate that the plugin doesn’t handle it gracefully. What I did was make my own define for IOS_BUILD at the top of PreciseLocale.cs

#if UNITY_IOS && !IOS_SIMULATOR	// The iOS plugin for this crashes in the simulator, so don't use it if in simulator mode.
#define IOS_BUILD
#endif

Then in the rest of the code, replace UNITY_IPHONE with IOS_BUILD (UNITY_IPHONE is considered obsolete anyway, so the author should change it).

Then, when you want to build for the simulator, you have to add IOS_SIMULATOR to the Scripting Define Symbols under “Other Settings” on the build settings (a little bit under where you have to choose “Simulator SDK” for Target SDK).

Of course, the downside to this hack is that it uses the default settings in the simulator, instead of the simulator’s settings, but you can temporarily change them in code if you need to test other values.

Guys, I am sorry but will check it next week since I am out now. Frankly I’ve never run Unity app in simulator.

Hey Piotr,

is there any update on this?

Since Facebook asks for a Simulator build for their submission this problem is kind of a hassle…

[Piotr]

Yes, I’ve checked this issue and Unity simply does not support iOS plugins working on simulator.

As a workaround (so it will use the same dummy values as in Editor):
1. Open PreciseLocale.cs
2. Replace it content with this:

#if UNITY_IOS && !IOS_SIMULATOR
#define IOS_BUILD
#endif

using UnityEngine;
using System.Collections;
using System.Runtime.InteropServices;
using System;

        string GetCurrencyCode();

        string GetCurrencySymbol();
    }

    private class EditorBridge : PlatformBridge
    {

        public string GetRegion()

3. Go to PlayerSettings and under Scripting Define Symbols put IOS_SIMULATOR, just like here: https://monosnap.com/file/I6roysuGhvcjyvbVajHwGUWwSvFuCg

Let me know if that worked for you.
