Impossible to verify the signature

[Kanunnikoff]

And I don't see recoverPubkeyFrom(signature, message) method in the Crypto.h in my project (but it is there in Git: https://github.com/TrustWallet/trust-core/blob/master/Sources/Crypto.h) - is CocoaPods version so old? I can't invoke that method.

Here https://github.com/TrustWallet/trust-core/blob/08cecb0d655df1b3fc250a36a9912bde2ca701a3/Tests/CryptoTests.swift I see let data = Crypto.recoverPubkey(from: signature, message: hash)!, but can't invoke Crypto.recoverPubkey(from, message) too.

@dmitry-kanunnikoff make sure you run latest TrustCore lib

[Kanunnikoff]

@vikmeup Just checked:

Using TrezorCrypto (0.0.8)
Using TrustCore (0.2.2)
Using TrustSDK (0.0.1)

It is the latest from CocoaPods.

@dmitry-kanunnikoff can and point to the master? we don't always push to cocoapods updated version

[Kanunnikoff]

@vikmeup Could you, please, tell how can I do that? I'm not a Xcode professional, and can add pods only.

[vikmeup]

You can just specify in your pod file for each module

pod 'TrustCore', :git=>'https://github.com/TrustWallet/trust-core', :branch=> 'master'

Mm, thank you very much! All works now! The signature's verifying is correct. Your help was really great!
@vikmeup Please, look at the similar issue on Android: trustwallet/TrustSDK-Android#10
Seems, signature is not ok there.
