Remark 7.1.5.11. Let $U: \operatorname{\mathcal{C}}\rightarrow \operatorname{\mathcal{D}}$ be an inner fibration of $\infty$-categories and let $K$ be a simplicial set. Using Remark 7.1.5.8, we see that a morphism $\overline{f}: K^{\triangleleft } \rightarrow \operatorname{\mathcal{C}}$ is a $U$-limit diagram if and only if every lifting problem

$\xymatrix@R =50pt@C=50pt{ \operatorname{\partial \Delta }^{n} \star K \ar [r]^-{\rho } \ar [d] & \operatorname{\mathcal{C}}\ar [d]^{U} \\ \Delta ^{n} \star K \ar [r] \ar@ {-->}[ur] & \operatorname{\mathcal{D}}}$

admits a solution, provided that $n \geq 1$ and the the restriction of $\rho$ to $\{ n\} \star K \simeq K^{\triangleleft }$ coincides with $\overline{f}$.
