I am trying to come up with regex to validate iOS app's bundle id. This link was quite helpful. However I also need to validate length of supplied bundleid as well as length of strings between dots (here I am assuming there would be such restrictions from Apple) . For example, in bundle id 'com.company.project' I need to ensure 'company', 'project' etc are also within in allowed limit. I tried finding any apple docs that talks about maximum allowed bundle id but I couldn't. Is it like any length is allowed? Any help appreciated.

Apparently 155 characters.
Checked in Apple Developer Account as seen below:
Also, it could be one long character set without .'s

From inspecting the HTML of the create App ID page on May 14, 2018, here are the constraints including a regular expression to validate the bundle identifier:
Name
- Maximum Length: 50
- Pattern:
^[0-9A-Za-z\d\s]+$
Bundle Identifier
- Maximum Length: 155
- Pattern:
^[A-Za-z0-9\.\-]+$
The original question was a regular expression to validate bundle identifiers, you could use this to do that:
^[A-Za-z0-9\.\-]{1,155}$

I think the regex should be `^[A-Za-z0-9\.\-]{1,155}$` - no + sign. + means "1 or more". – craig65535 Oct 03 '18 at 21:15
