[BUG] 0.32.2 causes iOS app to crash at launch on a physical iPhone running iOS 26.2

Describe the bug
The crash appears to be related to this code introduced/used by the package:

logger.isEnabled(type: level)

Crash
dyld[51571]: Symbol not found:
_$s2os6LoggerV9isEnabled4typeSbSo0a5_log_E2_ta_tF

Expected in:
/usr/lib/swift/libswiftos.dylib

To Reproduce

Just run on a physical iPhone

Desktop (please complete the following information):

OS Version: iOS 26.2
Device: iPhone 13
Version 0.32.2
Xcode Version: 26.6

Additional context
Add any other context about the problem here.

I'll take a look in the morning. From the message it looks like:

            if logger.isEnabled(type: level) {

but that api is available on iOS:

@available(macOS 11.0, iOS 14.0, watchOS 7.0, tvOS 14.0, *)
public struct Logger : @unchecked Sendable {

    public func isEnabled(type: OSLogType) -> Bool

What version of iOS 26 did you use? I just checked a device I have running 26.4 and the symbol is present.

It's iOS 26.2

OK, found the issue (incorrect availability on that method). Looking into replacement -- I will prepare a patch release with this. Thanks for the report!!

@davidkoski I think the cleanest fix for this would be to use OSLog.isEnabled (which is present on 26.2) and initialize Logger with OSLog

Agreed, but it doesn't work :-). Well, it is marked as unavailable, so it is a build error :-)

See #493 -- I tested that on 16.2 and it runs.

ah, just saw this - I'll rework my PR

could you share the specific error + your Xcode version? it seems to compile fine for me on Xcode 27.0 beta, build 27A5237l

🎉 Hope we’ll see a new release soon

I am on 27A266a (27.0 release build) and see:

'os_log_type_enabled' has been replaced by instance method 'OSLog.isEnabled(type:)'
'os_log_type_enabled' was obsoleted in Swift 3
