Making a new app based on an earlier version. Compile is clean and when the simulator starts to load I get the following failure"The file “XXXXXXX.app” couldn’t be opened because you don’t have permission to view it."I have checked the file and the file permissions are fine -- full read/write for user (me); read only for group; read only for everyone. The group is "staff" which is normal. In addition, these are the same file permissions on other ddd.app files in projects where the simulator does load and run correctly.I can't figure out what is wrong. O have compared the Build Settings for this project with other projects that do work but they are virtually identical. One difference is Framwork Search Paths is blank while other project have a path provided. If I do provide a similar path it gives a compile time warning that the framework file at path is missing. Doesn't seem like the problem area.Any ideas or assistance is appreciated!DetailsThe file “XXXXX.app” couldn’t be opened because you don’t have permission to view it.Domain: NSCocoaErrorDomainCode: 257Failure Reason: You don’t have permission.Recovery Suggestion: To view or change permissions, select the item in the Finder and choose File > Get Info.User Info: { NSFilePath = "/Users/me/Library/Developer/Xcode/DerivedData/XXXXX-ghyzcezhyezecqgdplhcjfduozjl/Build/Products/Debug-iphonesimulator/XXXXX.app";}--The operation couldn’t be completed.

I have a problem with the display of HTML code within my iOS app using WKWebView. Specially, the problem is line spacing. With iOS 12-13 the following code produces text (flowing around an image and footer) with the top of the image aligned with the top of the flowing paragraph. This display has been stable through the development and release. It is consistent with both simulators and physical devices. With iOS 14 (Beta 1 and noe Beta 2) the code produces the first line of the paragraph text overlapping the image top (although slightly below the top edge) and then flowing the rest of paragraph around the image. It looks terrible and, of course, makes the first line almost impossible to read. Perhaps this is a small bug but it breaks expected results and tarnishes the look and feel of the text in the eyes of the user. This is the case both using the Simulator and on an iPhone Xs. <-----------------------------------------------------> Here is the css file: #rp {     float: right;     margin: 0 0 0 15px; } #lp  {     float: left;     margin: 0 15 0 0px; } ...and the HTML in question:         <table style="width:80%; margin: 0px auto;">             <tr>                 <td>                     <p>                     The first stored program computer is typically attributed to the Babbage Analytical Engine that was programmed via punched cards. Certainly, a case can be made that Jacquard's loom fits as a programmable device but it doesn't fit a definition of computer. Similarly Pascal's calculator fits close to our concept of a computing device but isn't exactly programmable.                     <p>                     While programmable, mechanical computers, manufacturing devices and calculators fit in the evolution of the modern computer they each share a fundamental flaw... it's really hard to change the machine to explore new results. There must be a better approach.                     <p>                     A solution for this problem resulted from the discovery of electricity. This magical property quickly found its way into the computer world as a marriage between mechanical structures and simple wires to carry current that controlled how the machine would operate. This was much more practical than steam that powered both Bababage's Difference Engine and his Analytic Engine.                                        <p>                     <div style="text-align: right;" id="rp"/>                     <figure>                         <img src="punchcard.png" width="400" >                             <figcaption>80-column Hollerith Punch Card                             </figcaption>                             </figure>                     </div></p>                     <p>                     The machines were able to manipulate media to carry out roles and functions much faster than humans.

Small metal brushes create a small electrical circuit to be completed when the brushes pass over a hole. </p>                     <p> <----------------------------------------------------->

The Apple Help function is pretty awful and has been for ages. I assume part of the problem is the lack of documentation about how to add Help to an App. I have created a Help Bundle but can't figure out how to add it to my app. The /Resources folder is missing and it doesn't appear to be accepted if added manually. Any help or document that will make this easier to figure out would be great! NOTE: This is an iOS app running on MacOS as a Catalyst supported function -- not a native MacOS app.

How do you determine if your iOS app is running on MacOS? Currently, I am using the following code:     var weHaveMac = false         if #available(iOS 14.0, *) {         if  UIDevice.current.userInterfaceIdiom == .mac {             weHaveMac = true             print ("Mac?: \(weHaveMac), system?: \(UIDevice.current.userInterfaceIdiom)")         }     } But, the UIDevice.current.userInterfaceIdiom == .Mac test always returns false. I am using Xcode 12.2 Beta with MacOS 11.0.1 Beta.
