Hi Matt,
I had run into a similar problem.
When we use tool - SwiftyRSA to encrypt and decrypt data and send it to backend, it was working successfully until I have updated Xcode to 11.4
Using the same code which compiled from Xcode 11.3.1 can encrypt and decrypt, but failed randomly in the release environment on v11.4.
Do you have any ideas or suggestions on how we should solve this issue?

func startTest() {
var pubKey: PublicKey?
var priKey: PrivateKey?
do { //RSA Public Key AAA.pem
pubKey = try PublicKey(pemNamed: "AAA")
//RSA Private Key BBB.pem
priKey = try PrivateKey(pemNamed: "BBB")
} catch {
}
var errorCount = 0
let testCount = 1000
var round = 0
var testTimer: Timer?
testTimer = Timer.scheduledTimer(withTimeInterval: 0.01, repeats: true) { (timer) in round += 1
if round < testCount { guard let publicKey = pubKey, let privateKey = priKey else {return} let time = Date().timeIntervalSince1970
let timeStr = String(Int(time * 1000))
var plainStr = ""
do { let clear = try ClearMessage(string: timeStr, using: .utf8)
let encrypted = try clear.encrypted(with: publicKey, padding: .PKCS1)
let cypherStr = encrypted.base64String
let encryptedB = try EncryptedMessage(base64Encoded: cypherStr)
let clearB = try encryptedB.decrypted(with: privateKey, padding: .PKCS1)
plainStr = try clearB.string(encoding: .utf8)
} catch { plainStr = error.localizedDescription
}
if timeStr != plainStr { errorCount += 1
print("string: \(timeStr), plainStr: \(plainStr)") print("round: \(round), errorCount: \(errorCount)") } else { print("round: \(round), errorCount: \(errorCount)") }
} else { testTimer?.invalidate()
testTimer = nil
print("round: \(round), errorCount: \(errorCount) failed: \(Float(Float(errorCount)/Float(round)))") }
}
}
