verify(amount:transaction:precomputedData:inputIndex:flags:)

Verifies whether a transaction input spends this script pubkey.

func verify(amount: Int64, transaction: Transaction, precomputedData: PrecomputedTransactionData? = nil, inputIndex: UInt32, flags: ScriptVerificationFlags = .all) -> (valid: Bool, status: ScriptVerifyStatus)

Parameters

amount: The amount associated with this output (used when witness flag is set).
transaction: The spending transaction.
precomputedData: Pre-computed transaction data (required for taproot).
inputIndex: Index of the spending input in the transaction.
flags: Script verification flags controlling validation.

Return Value

A tuple of (valid, status) where valid indicates if the script passed, and status provides details on failure.
