Maybe the folder was not uploaded to iCloud yet. Otherwise they should be there on icloud.com.

If your files are stored in the "iCloud" location in Textastic, you can recover them on iCloud.com: 

• login with your Apple ID on icloud.com
• go to Settings on icloud.com
• go to Recover Files in the Advanced section
• there you can select the files you want to restore

Files in "Local Files" can only be restored if you restore a complete iPhone backup.

On iPad, you can still drag a folder from Working Copy into the side bar of Textastic to open it as explained in the manual at https://www.textasticapp.com/v8/manual/integration_other_apps/git_client_working_copy.html#use-drag-and-drop-on-ipad-to-open-a-repository

Yes, this is planned for a future update.

Thanks!

Just after sending my reply I think I could reproduce the problem: in landscape, the first three buttons didn't respond anymore for me. Looks like a glitch in the beta that is hopefully fixed in an update.

Hello,

I cannot reproduce the problem on my 11" iPad Pro running iOS 13 beta 3.

Pressing the tab key works on the on-screen keyboard itself and in the additional row of keys above the keyboard. It also works for me with an external keyboard.

Does a reboot help? If it doesn't, can you please send me a short video?

Here is another part of the docs with more details:

Numbers within strings are compared using numeric value, that is, Name2.txt< Name7.txt < Name25.txt.
Numeric comparison only applies to the numerals in the string, not other characters that would have meaning in a numeric representation such as a negative sign, a comma, or a decimal point.

Hello,

Textastic 8 now uses the same file name sorting as Finder. Here is a screenshot of Finder on macOS 10.14:

"06" is interpreted as the number 6, "7F" as 7, "08" as 8, "75" as 75. 

Textastic uses the API NSString.localizedStandardCompare. From the docs:

Compares strings as sorted by the Finder. This method should be used whenever file names or other strings are presented in lists and tables where Finder-like sorting is appropriate. The exact sorting behavior of this method is different under different locales and may be changed in future releases. This method uses the current locale.

The big advantage is that files like this now sort correctly:

file 8

file 9

file 10

file 11

Previously "file 10" and "file 11" would be shown before "file 8".

I'm sorry that this messes up your naming scheme. As a workaround, you can either add a number like "1" as a prefix to all file names or not mix numbers and letters in your naming scheme to get the correct sorting.
