it cost me longlong time to parse

[leewaycn]

just as above,
it cost me a 12 seconds to parse a fit file just size 570k bytes.
How could it be so slowly, damn it
please help me to fix this horrible problem

[leewaycn]

I use time profiler to check there is some cost-time fun to use OrderCollections.
I don't know why you use it . but consider my App don't need it, so I remove OrderCollection and change it to Normal Dictionary.
Here is my modified link : https://github.com/leewaycn/fit-swift-sdk
I hope you can change it as above

同样的问题。但是用https://github.com/garmin/fit-objective-c-sdk 解析很快。
官方fit-swift-sdk 这个库的解析为什么这么慢？

[lipopli]

Could the official solve the problem of slow parsing? I really want to use the fit-swift-sdk library

I confirm the SDK is super slow at decoding. @lipopli At this point you should just ask Codex / CC to implement a custom parser. Encoding seems ok though, personally I'm using the official encoder for protocol compliance and a custom one for decoding (more performant)
