iOS app crash when using TextMeshPro UGUI in scene (case 1153191)

Unity Engine
, ,
1

@Stephan_B hoping to get your eyes on this as it seems to be related to TextMesh Pro.

I’m having an issue where the built iOS app will crash with Exception Type: EXC_CRASH (SIGABRT) if I have a scene with a canvas containing a TextMesh Pro UGUI component. Removing the text component, the scene will load fine without any problems. I have reported this with case # 1153191.

Weirdly this only happens intermittently when doing a local build, but happens always with a build from Unity Cloud Build.

Any help with this issue would be much appreciated.

Hey @steego do you use the latest version of TM Pro? I remember I had this issue with an old version, updating TMP Pro remove it.

3

@Aymeric_1 thanks for the suggestion, but this is with the latest version, 2.0.1, using Unity 2019.1.

4

I’ll try taking a look at the case tomorrow.

Did you have a chance to take a look?

@Stephan_B Any news?

I’ve added TextMeshPro in my game and it crashes on iOS when the scene containing the TextMeshPro gameObject is loaded.

  • TextMeshPro version : 2.0.1
  • Unity version : 2019.1.13f1

Please be sure to test with the latest release for Unity 2019.x which is version 2.1.0-preview.3 and let me know if the issue persists.

Hello @Stephan_B ,

Sorry for the late reply, I didn’t have time to test before today. For an unexplainable reason, it worked today with the 2.0.1 version of TextMeshPro.

Because of the issue last week, I used the plain Text component, and removed Text Mesh Pro Essentials I had imported, but kept "com.unity.textmeshpro": "2.0.1" as dependency in my packages

Then, today, I reimported TMPro Essentials, triggered a build on my C.I and it worked.

  • Ipad Mini iOS 12
  • Ipod Touch iOS 11
  • Ipad Pro iOS 12
  • iPhone XR iOS 13

I hope I won’t have any issue in the future. If so, I will try to update to 2.0.1-preview.3

@Stephan_B

With the TextMeshPro 2.1.0-preview3 version, I don’t get the crash anymore on iPhone XS iOS13.3. I’ve also tested on an Ipad Pro iOS 12 and iPhone XR iOS 13 and everything worked well.

However, since it’s a preview package, can I serenely ship my game?

Preview 4 should be available within a day or two. I would suggest testing that latest release once available and that if everything appears to be working as expected on your end that you should be fine moving forward with it.
