init(literalCapacity:interpolationCount:)

Creates an empty instance ready to be filled with string literal content.

Declaration

init(literalCapacity: Int, interpolationCount: Int)

Parameters

  • literalCapacity:

    The approximate size of all literal segments combined. This is meant to be passed to String.reserveCapacity(_:); it may be slightly larger or smaller than the sum of the counts of each literal segment.

  • interpolationCount:

    The number of interpolations which will be appended. Use this value to estimate how much additional capacity will be needed for the interpolated segments.

Discussion

Don’t call this initializer directly. Instead, initialize a variable or constant using a string literal with interpolated expressions.

Swift passes this initializer a pair of arguments specifying the size of the literal segments and the number of interpolated segments. Use this information to estimate the amount of storage you will need.
