// FIXME: The SPIs above can be declared by WebKit without causing redeclaration errors on Catalina
// internal SDKs because we can avoid including the SPIs' private headers from PassKit, but we can't
// avoid importing PKPaymentSetupFeature.h due to how many other private headers include it. To avoid
// redeclaration errors while continuing to support all Catalina SDKs, declare -supportedOptions
// only when building against an internal SDK without PKPaymentInstallmentConfiguration.h (so that we
// can implement a -respondsToSelector: check). The __has_include portion of this check can be
// removed once the minimum supported Catalina internal SDK is known to contain this private header.
