[iOS] 16.1.1 still has UI thread violation: [UIApplication supportsMultipleScenes]

Question

It looks like Intercom.logEvent(withName: ) is not thread safe, Yet the in line documentation is not warns the user and the provided url is broken: “Log an event with a given name. You can log events in Intercom based on user actions in your app. Details about Events here “Broken url: https://developers.intercom.com/reference/#events Workaround:Intercom.logEvent(withName: event) should be called on main thread only. Solution:Make sure Intercom.logEvent(withName: event) is thread safe or make it clear if its not.Stack trace:Main Thread Checker: UI API called on a background thread: -[UIApplication supportsMultipleScenes]PID: 16482, TID: 5635365, Thread name: (none), Queue name: com.apple.NSXPCConnection.m-user.com.apple.photos.service, QoS: 0Backtrace:4   Intercom                            0x0000000105475054 IntercomSDK_PINRemoteImageManagerSubclassOverridesSelector + 8106205   Intercom                            0x00000001053f3c44 IntercomSDK_PINRemoteImageManagerSubclassOverridesSelector + 2811966   Intercom                            0x00000001053f38a0 IntercomSDK_PINRemoteImageManagerSubclassOverridesSelector + 2802647   Intercom                            0x000000010522a9e4 Intercom + 271088   Intercom                            0x000000010522a29c Intercom + 252449   Teleprompter                        0x0000000100b22948 $s12Teleprompter12EventManagerC011logIntercomB033_1768655BADB6CC7E572E42D4AE426D1BLL_10parametersySS_SDySS8Mixpanel0N4Type_pGSgtF + 33210  Teleprompter                        0x0000000100b22438 $s12Teleprompter12EventManagerC03logB0_10parametersySS_SDySS8Mixpanel0F4Type_pGSgtF + 9611  Teleprompter                        0x00000001009d1138 $s12Teleprompter26VideoPreviewViewControllerC9exportTapyyypFySb_s5Error_pSgtcfU0_ + 134012  Teleprompter                        0x00000001009d1cb4 $sSbs5Error_pSgIegyg_SbSo7NSErrorCSgIeyByy_TR + 13613  Photos                              0x00000001c4bf7ae8 98DE7C60-A169-383D-846D-104DDE07D15E + 96535214  Photos                              0x00000001c4bf9670 98DE7C60-A169-383D-846D-104DDE07D15E + 97240015  Photos                              0x00000001c4bf9094 98DE7C60-A169-383D-846D-104DDE07D15E + 97090016  Photos                              0x00000001c4bf8c8c 98DE7C60-A169-383D-846D-104DDE07D15E + 96986817  CoreFoundation                      0x00000001add27134 CEB74A0C-5EA4-3F5A-9DE8-73F0DAD2F4CB + 20510818  CoreFoundation                      0x00000001add26bcc CEB74A0C-5EA4-3F5A-9DE8-73F0DAD2F4CB + 20372419  Foundation                          0x00000001accfcf20 60F744F4-1345-325E-8970-D37BB5A1A31D + 44624020  Foundation                          0x00000001accfcaa0 60F744F4-1345-325E-8970-D37BB5A1A31D + 44508821  Foundation                          0x00000001accfc408 60F744F4-1345-325E-8970-D37BB5A1A31D + 44340022  libxpc.dylib                        0x0000000216f3eb44 8E13493A-AC3E-3EEF-8B3E-102A3D715B23 + 12576423  libxpc.dylib                        0x0000000216f314b4 8E13493A-AC3E-3EEF-8B3E-102A3D715B23 + 7083624  libdispatch.dylib                   0x00000001049f2bb4 _dispatch_client_callout3 + 2025  libdispatch.dylib                   0x0000000104a11ca8 _dispatch_mach_msg_async_reply_invoke + 39226  libdispatch.dylib                   0x00000001049fa7c4 _dispatch_lane_serial_drain + 37627  libdispatch.dylib                   0x00000001049fb75c _dispatch_lane_invoke + 46028  libdispatch.dylib                   0x0000000104a085f8 _dispatch_root_queue_drain_deferred_wlh + 32829  libdispatch.dylib                   0x0000000104a07c2c _dispatch_workloop_worker_thread + 44430  libsystem_pthread.dylib             0x0000000216ede964 _pthread_wqthread + 28831  libsystem_pthread.dylib             0x0000000216edea04 start_wqthread + 8
