I am a solo developer at a government agency. This presents some interesting challanges. First and foremost, I create apps that are not able to access internet resources, and thus I don't have access to some tools that would provide the easy answer to a lot of my problems.My current problem is that I don't have the ability to use some of the very robust error handeling products out there. However, I need a way to capture crashes on devices that are not teathered to my workstation. I need robust reporting and the ability to see logs for anything that happened on devices that are deployed in places that are not accessable to me easily (think maximum security portion of a ****).My current thought is capturing every error and sending it to an internal webservice. However, I don't know how to do this without surronding every single line in a try catch. Does anyone have any experience with this, or with something else entirely that would get me the information I need to debug crashes?Thanks in advance

I am attempting to get a new iPad running an enterprise app to run in single app mode. However, I get the following error:An unexpected error has occured with "iPad".The profile must be installed using a device management tool. [MCInstallationErrorDomain - 0xFB4 (4020)]I have the ipad on ipadOS 13 because the app is utilizing some of the new USB/SD file management features.I am not sure how to fix this issue as I have wiped the device several times and get the same error, and I get the same error regadless of what app I try to run in single app mode. I am trying to run Safari assuming that is a safe app, yet it still throws the error.
