I want use SHLibrary.default.items to show the music i recognized by Shazam. but SHLibrary.default.items always return empty list.
I did an experiment and I called SHLibrary.default.items as soon as I entered on a page and it returned an empty list, but after use SHManagedSession to identify songs and then call SHLibrary.default.items it returned the result I wanted. Below is the test code
private func bindEvent() {
// call when View was create the items return empty
if #available(iOS 17, *) {
let items = SHLibrary.default.items
print("-------->>>>>>>>\(items)")
}
self.addToMediaLibray.onTap { [weak self] in
guard let `self` = self, let result = self.result, let appleMusicID = result.appleMusicID else { return }
if #available(iOS 17, *) {
// call when music was recognized the item is not empty.
let items = SHLibrary.default.items
print("1111-------->>>>>>>>\(items)")
}
}
}
The attach file is the part of result log
My iOS Verion is iOS 17 (21A5326a) XCode Version is 15.0 beta 8 (15A5229m)

The song detection is successful however with new APIs,
I can't find this demo working with SHLibrary, it expect to display the RecentDanceRowView.
I wonder if I missed any steps or the SHLibrary is not ready yet.

Looking to fill up a budget line for an iOs application we are trying to build.
By adding ShazamKit to our app, how much cost the use of it per stream ?
My research indicates that it is 0,00065$, correct ?

When I watch the ShazamKit Session Video the presenter mentions downloading a sample project from the developer portal, but there is no link to the sample project. Where can I find it? Thanks.

Hi,
I am using ShazamKit to detect songs from a live stream. I am using matchStreamingBuffer with a PCMBuffer. It looks like it works for the most part, but sometimes it throws an NSException.
Here's the code calling the match:
engine.mainMixerNode.installTap(onBus: 0, bufferSize: 4096, format: options.audioFormat) { buffer, time in
do {
self.session.matchStreamingBuffer(buffer, at: time)
}
catch {
}
}
The exception:
Supplied audio format is not supported <CMAudioFormatDescription 0x2828a29e0 [0x20f7863a0]> { mediaType:'soun' mediaSubType:'lpcm' mediaSpecific: { ASBD: { mSampleRate: 44100.000000 mFormatID: 'lpcm' mFormatFlags: 0x29 mBytesPerPacket: 4 mFramesPerPacket: 1 mBytesPerFrame: 4 mChannelsPerFrame: 2 mBitsPerChannel: 32 } cookie: {(null)} ACL: {Stereo (L R)} FormatList Array: { Index: 0 ChannelLayoutTag: 0x650002 ASBD: { mSampleRate: 44100.000000 mFormatID: 'lpcm' mFormatFlags: 0x29 mBytesPerPacket: 4 mFramesPerPacket: 1 mBytesPerFrame: 4 mChannelsPerFrame: 2 mBitsPerChannel: 32 }} } extensions: {(null)} }

I don't mind failing if the format is not good, but how can I avoid crashing?
Ruizhe.
